Istanbul is a year-round city, but the weather, crowds and prices swing a lot through the year. Here’s a month-by-month guide to help you choose.
Istanbul by season
| Season | Weather (typical highs) | Crowds & prices | Verdict |
|---|---|---|---|
| Spring (Apr–May) | 16–22°C, mostly dry | Busy, mid-high prices | ★★★★★ Tulip season |
| Summer (Jun–Aug) | 25–29°C, humid | Peak crowds and cruise ships | ★★★ Hot, but long evenings |
| Autumn (Sep–Oct) | 20–26°C, warm sea | Busy in Sep, easing in Oct | ★★★★★ Ideal |
| Winter (Nov–Mar) | 8–12°C, rain, some snow | Quiet, cheapest | ★★★ Good for museums |
Spring: tulips and mild weather
In April, the city plants millions of tulips for the Istanbul Tulip Festival. Emirgan Park and Gülhane Park are the stars. Days are pleasant for walking, though evenings can be cool, so pack a light jacket.
Summer: hot and crowded
July and August bring the most visitors, the longest queues at Hagia Sophia and Topkapı, and humid heat. Sightsee early, rest at midday and spend evenings on rooftops or ferries. Book hotels well ahead.
Autumn: our favourite
September still feels like summer, and October is golden and comfortable. Queues shrink after the summer rush, and it’s a great time for a Bosphorus cruise or a day on the Princes’ Islands.
Winter: cheap and atmospheric
Winters are grey and wet rather than freezing, but snow on the domes happens most years. Hotel prices drop, and the museums, hammams and covered bazaars are perfect on rainy days. New Year is the exception, when prices spike.
Ramadan and holidays
During Ramadan (expected around mid-February to mid-March 2027), sights stay open, and evenings around the Blue Mosque come alive with iftar stalls. Some opening hours shift. During the Eid holidays (Ramazan Bayramı and Kurban Bayramı), many Turks travel, so transport and resorts get busy, though central Istanbul can feel quieter. Exact dates follow the lunar calendar, so check them before you book.
